This package consists of an API for a doubly linked list. The API is divided into six functional groups: initialization, status and state, pointer manipulation, list update, search, and input/output. The API has been used in production software for over 10 years.

Kodo JDO allows you to write database calls using Java statements instead of SQL statements, by supporting the Java Data Objects standard for transparent persistence. It is the most complete implementation of the JDO specification for relational data stores, and comes with tools for producing a schema from an object model, producing class files from an existing schema, and a performance pack (distributed caching and statement batching) that improves performance by 15 - 30 times. It supports most relational databases, application servers, and IDEs, and reduces the total coding effort by 20-40%.

KInterbasDB is a Python extension package that
implements Python Database API 2.0-compliant
support for the open source relational database
Firebird and some versions of its proprietary
cousin Borland Interbase. In addition to the
minimal feature set of the standard Python DB API,
KInterbasDB also exposes nearly the entire native
client API of the database engine.

The libmba package is a collection of mostly independent C modules potentially useful to any project. There are the usual ADTs including a linkedlist, hashmap, pool, stack, and varray, a flexible memory allocator, CSV parser, path canonicalization routine, I18N text abstraction, configuration file module, portable semaphores, condition variables, and more. The code is designed so that individual modules can be integrated into existing codebases rather than requiring the user to commit to the entire library. The code has no typedefs, few comments, and extensive man pages and HTML documentation.

Daffodil DB is a SQL-99 specification compliant, lightweight, Java-based relational database engine (RDBMS). It supports almost all constructs of SQL 99 (including triggers, views, constraints, UDT, stored procedures, etc.), supports distributed transactions (XA), provides a complete JDBC 3.0 driver (including support for optional features like save points, rowsets, UDT, XA, connection pooling, etc.), and can run in embedded or server mode. It can be included as a jar file in any Java application. Daffodil DB includes Daffodil DB Browser, a GUI-based database management tool that can be used to carry out all database operations such as creating a database, creating database objects, executing SQL statements, and manipulating data, browser database objects, etc.
